When it's time to capture the traffic, limit the packet capture to 1,000-2,000 packets so that you have a consistent capture size for the baselines. The process of capturing should be documented; for example, where and what time of day it was and what equipment you used during capture.
The key is to be as consistent as possible with your captures, so you compare apples to apples. If you select Statistics and then Capture File Properties, you can add a comment to provide additional information about the capture, as shown in the following screenshot:
The Capture File Properties window
After you complete the capture phase, we then move to the analyze phase, where we take a look a closer look at the capture.
